Definitions

  • the invention relates to a method and a device according to the preambles of the corresponding independent claims.
  • Method and apparatus are used to produce stacks of substantially continuously fed flat objects, in particular printed products such as e.g. Newspapers, magazines, brochures or partial or intermediate products of newspapers, magazines or brochures.
  • the printed products are usually further fed by the newly fed print products in a stacking direction transverse to the feed direction, being substantially transverse to the stacking direction and aligned with each other, with a downstream end of the stacked arrangement supported and wherein the printed products are arranged so tightly that they stabilize each other in the substantially upright posture.
  • the downstream end of the stack-like arrangement are then discrete stacks, each having a predetermined number of printed products or a predetermined length, separated and fed, for example, a strapping or packaging.
  • the device according to the invention should be simple and in particular should be easily adaptable to different formats of flat objects to be stacked.
  • the flat objects are thus supplied as a scale flow, in which they are arranged substantially upright, that is their areal extent is oriented approximately vertically, fed in a feed direction of an inlet point.
  • they meet with their leading edge on a transversely aligned to the feed direction aligning element and are deflected by this by about 90 ° and thereby arranged in a stack.
  • the stack-like arrangement grows in an, for example, horizontal stacking direction along the alignment member with its downstream end supported and periodically discrete stacks separated from this downstream end.
  • the stack-like arrangement is now divided into an inlet-side loosener part and a downstream, dense part, characterized in that in an action region, which is spaced from the inlet point in the stacking direction, the stacked objects are accelerated in the stacking direction such that it accelerates against the downstream end of the stack-like assembly and pushes it against the objects already there.
  • the stack-like arrangement is compacted by this action in the area of action and downstream thereof while being loosely held between the area of action and the point of entry. The accelerating effect is exerted on two opposite edge regions of the objects.
  • Objects that are newly fed at the point of entry of the stack-like arrangement are thus pushed into the loose part of the stack-like arrangement, so that this supply opposes a significantly smaller resistance than is the case when all of the newly supplied objects in the stack-like Arrangement present objects are to be moved in the stacking direction. Furthermore, this resistance is independent of the instantaneous length of the stack-like arrangement. The effect is advantageously enhanced by actively moving the objects in the loose part of the stack-like arrangement not only by the newly supplied objects but also by suitable means in the stacking direction.
  • the loose arrangement of the objects on the first path in the stacking direction allows not only an almost resistanceless feed, which is easily possible for less stable objects, but also a secure alignment of the objects on the alignment and possibly by additional, the objects successive means, which Orientation in the loose arrangement is less obstructed by adjacent objects, as would be the case in a dense arrangement.
  • the device essentially comprises the following parts: a supply means for the supply of upright and overlapping arranged objects, an aligning element for deflecting the supplied objects in a stack-like arrangement, means for guiding and supporting the stack-like arrangement, a separating means for pushing together loose and compacted part of the stack-like arrangement to a stack and a compression means which acts in the stacking direction spaced from the inlet point Einwirk Scheme in the stacking direction accelerating acting on opposite edge regions of the stacked objects.
  • the means for guiding and supporting are advantageously made movable and provided in a plurality, so that the means can be separated with the stack and at the same time new means for a next stack can be positioned.
  • the stacking according to the invention has the advantage over conventional stacking devices of the same kind that the objects act mutually on one another in the area of the inlet point, ie immediately before and after their 90 ° deflection with only minimal forces, so that they are easily and accurately aligned for stacking even if they do not have great inherent stability.
  • the loose arrangement of the objects in the inlet-side part of the stack-like arrangement also makes it possible to easily bend the objects and thereby stabilized and stiffened, which likewise serves the exact deflection and alignment. Furthermore, it is easily possible to supply thicker points in the scale flow (heap).
  • FIG. 1 shows an exemplary embodiment of the inventive device 1.
  • This device is supplied via an arbitrary feed 2, a shingled stream of flat objects 3, for example, of folded or bound printed products, of which stack 4 are formed.
  • the device 1 essentially has an inlet part 5 and a stacking part 6, which cooperate for the stack formation.
  • the essential components of the inlet part 5 are feeding means, for example feed belts 5.1 and 5.2, an aligning element 5.3, a compression means 5.4 and a separating element 8.
  • the feed belts 5.1 and 5.2 are used for feeding the scale flow, wherein the articles 3 for feeding substantially upright in the scale flow are arranged.
  • the alignment element 5.3 is arranged transversely to the feed direction 5.10 and serves to deflect the supplied objects from the feed direction 5.10 in the stacking direction 4.3, to their orientation and possibly also to their movement in the stacking direction 4.3.
  • the compression means 5.4 arranged in an action region 5.12 serves for the compression of the downstream part of the stack-like arrangement 4 '. His Function will be related to the FIGS. 2 to 4 described in more detail.
  • the separating element 8 is used to separate the supplied scale flow and the sliding of the loose part on the compacted part of the stack-like arrangement 4 '.
  • the flat objects 3 are conveyed in the feed direction 5.10 between the at least two endless belts 5.1, 5.2 against the alignment element 5.3. At the inlet point 5.11 they meet with their leading edge against the extending transversely to the feed direction 5.10 alignment element 5.3 and are stacked and moved in the stacking direction 4.3 (perpendicular to the feed direction 5.10) along the alignment 5.3, on the one hand pushed by further supplied objects and advantageously actively moved in this direction, for example, characterized in that the alignment element 5.3 is formed as shown in the stacking direction 4.3 driven conveyor belt or has such a conveyor belt.
  • the stacking part 6 has at least two receiving devices 6.5, the essential components of which are a conveying support 6.2 and a support element 6.3.

  • the stack 4 is here on a support surface with grooves 6.7, in which engage the arms of a discharge device 7. With the help of the ejection device 7, the stack 4 is pushed out of the receiving device 6.5.
  • the receiving device 6.5 is rotated in the position indicated by III, and then in the position indicated by IV. It is advantageous in this case to couple the receiving devices 6.5 diagonally opposite one another in such a way that the support element 6.3 of a receiving device (position I) connected to the inlet part 5 is moved from its starting position to its end position, while in the recording device in position III the supporting element 6.3 is moved from its end position to the starting position. In positions II and IV, the support element is then stationary.
  • the separation of discrete stacks 4 from the stack-type arrangement 4 ' also serves the separating element 8 acting between the action area 5.12 and the inlet point 5.11, which is movably mounted for the exercise of its function in the vertical direction 8.1, 8.3 and in the horizontal direction 8.2, 8.4.
